Read the first 7 Water Efficiency Concepts flashcards as text

  1. Which alternative water source is most commonly permitted under LEED for toilet and urinal flushing?

    Answer: Rainwater harvested and stored on-site

    Harvested rainwater is a widely accepted non-potable alternative water source for toilet and urinal flushing in LEED.

  2. What is the primary goal of the LEED prerequisite 'Indoor Water Use Reduction'?

    Answer: Reduce potable water consumption by at least 20% compared to a baseline

    The prerequisite mandates a minimum 20% reduction in indoor potable water use compared to the EPAct 1992 baseline.

  3. Which of the following landscape design strategies earns the most LEED points for outdoor water reduction?

    Answer: Eliminating all irrigation for the entire landscape

    Eliminating all irrigation achieves the maximum outdoor water use reduction, earning the highest available points.

  4. In LEED, what occupancy type is used to calculate the number of full-time equivalent (FTE) occupants for water use baseline?

    Answer: 8-hour occupancy per person per day for FTEs, with transient occupants at fractional hours

    LEED uses 8 hours per FTE and assigns fractional hours to transient occupants based on their typical daily duration.

  5. A project replaces a cooling tower with an air-cooled chiller. What is the primary Water Efficiency benefit?

    Answer: Eliminates cooling tower makeup water, reducing process water consumption

    Air-cooled chillers eliminate the need for cooling tower makeup water, which can represent a significant portion of a building's total water use.

  6. What does 'cycles of concentration' measure in a cooling tower context within LEED?

    Answer: The ratio of dissolved solids in recirculating water versus makeup water, indicating water use efficiency

    Higher cycles of concentration mean less blowdown is required, reducing cooling tower water consumption.

  7. Which LEED certification system is most applicable to a large commercial office building pursuing water efficiency credits?

    Answer: LEED BD+C: New Construction

    LEED BD+C: New Construction is the rating system designed for new large commercial buildings including office projects.
